Ralph Pierce Reservoir viewed from the Sleepy Lion Trail. You can see Mt. Meeker in the distance.
Button Rock is a delightful and lesser-known open space just west of Lyons. It is dog friendly, contains views of distant Twin Sisters, and skirts a narrow reservoir bordered by pine trees. It is another of my favorite shoulder season hikes.
The trail starts off in a large dirt parking area surrounded by high cliffs. On the west side of a wide gate, a broad flat road heads east towards the Ralph Price Reservoir. The road transects the canyon with several interesting water features along the way. If you continue heading west, you will end up at the base of the dam, but for a more interesting route, take the Sleep Lion Trail around a half-mile up the road. A large sign marks the trail.
The Sleepy Lion Trail winds through Ponderosa and Douglas fir. There are occasional open meadows and isolated red boulder formations. At the high point you can see the tip of Mt. Meeker and the double hump of Twin Sisters. There are also views of the reservoir itself.
From the highest vantage, the trail descends down an old rail bed to the base of the dam. Here a dramatic jet of water shoots out of the reservoir’s water control feature. It is difficult to pull oneself away from the chaotic and powerful display of man’s attempt to control nature.
On the far right-hand side of the dam is a short but steep trail up to the reservoir itself. This ascends several hundred feet through several highly eroded areas. Anyone used to Colorado’s steep ascents will find this short jaunt to be trivial. For those who wish an outing that is easier on the knees, skip the trail and head back down the broad road to the trailhead.
The Ralph Price Reservoir is an interesting and rarely visited place. There is no official trail that circumnavigates it, but you can walk along the right shoreline for a mile or so. In low years, there are boulders to nestle in and in high years, the deep blue waters of the reservoir lap the shoreline almost to the level of the trail. If the wind is not blowing too much, this is a pleasant place for a picnic.
To return to the trailhead, the hiker has two options, he can return down to the base of the dam via the steep trail or wander up and around to one of the dirt roads that skirt the area.
On a sunny fall day, Button Rock can be a pleasant Front Range excursion. While known to the locals, it is rarely visited by those outside of Lyons. This does not mean that it will be uncrowded, however, but I have found that most visitors stay on the main road and do not take the more scenic but more strenuous Sleep Lion Trail.
